Java

The Spark The other day I came across a fascinating post on Substack by Skilled Coder about Java data structure performance. The post showed some eye-opening numbers for 10M operations: Get operations: HashMap.get() → ~140 ms TreeMap.get() → ~420 ms ArrayList.get(i) → ~40 ms LinkedList.get(i) → ~2.5 s Insertion (10M elements): ArrayList.add() → ~180 ms HashMap.put() → ~300 ms LinkedList.add() → ~900 ms This got me thinking: how do these numbers compare to Eclipse Collections? And more importantly, how can we calculate these numbers ourselves using open source tools? ...

Introduction Test results for this benchmark run → Over the last two days, I’ve expanded our microservice framework benchmark suite to include two new contenders: Golang and Express.js. This addition allows us to compare performance across a broader spectrum of technologies, from compiled languages like Rust and Go to JVM-based frameworks and Node.js. New Additions Golang (Go 1.24.10) Go was added using the standard library only - no external frameworks. The implementation uses net/http package which is known for its excellent performance and simplicity. ...
